I don’t know The answer but I tried
The area of the rectangle would be 45 m^3
Answer: The Area is 35 square centimeters.
Key:
B1 = Base #1
B2 = Base #2
H = height
* = multiply
/ = divide
Step-by-step explanation:
First, write down the formula needed: (B1 + B2) * H / 2 = Area
Now Fill in what you know:
(6 + 8) * 5 / 2 = Area
B1 is 6 cm
B2 is 8 cm
The Height is 5cm (TIP: the height is usually in a vertical direction).
&
The Area is still unknown
Let’s Answer the equation now:
(B1 + B2) * H / 2 = Area
(6 + 8) * 5 / 2 = Area
(14) * 5 / 2 = Area
70 / 2 = Area
Area = 35 square centimeter (cm).
I hoped this helped.
Answer: a = 18
explanation:
2(a + 10) = 56 -> distribute the 2
2a + 20 = 56 -> subtract 20 from both sides
2a = 56 - 20
2a = 36 -> divide both sides by 2
a = 18
A quadrilateral's angles sum to 360 degrees.
78 + 46 + 118 = 242
360 -242 = 118
